Why does it look like glass in my canned seafood?


This is completely normal in canned seafood. These are struvite crystals and are formed by the natural, normal constituents of seafood after it is sterilized in the can. The crystals are no harder than ordinary table salt and can be easily scratched and crushed to a powder with the thumbnail. They will dissolve in a few minutes in warm vinegar, as they do in stomach acid.
